Persistent storage on the Arduino Nano Matter?

[technoblogy]

Does the Arduino Nano Matter have any form of persistent storage capability? I need this for my application.

I’m thinking of one of the following possibilities:

• EEPROM. For example the ATmega328 used on the Arduino Uno provided 2 Kbytes of EEPROM, and this is provided or emulated in most subsequent Arduino boards.

• Flash storage. For example, the ATSAMD21-based boards support storage in the program Flash memory.

• LittleFS flash filing system. For example, the ESP32 and RP2040-based boards support storage in the program flash memory using the LittleFS filing system.

• DataFlash chip. For example, the Adafruit M4 and other "Express" boards include a DataFlash chip which can be used for persistent storage.

Thanks! David

Hello David,
EEPROM library support is coming in the next release!

[technoblogy]

Great! Look forward to trying it out.

Hello @technoblogy,
EEPROM library support is now available with 2.1.0.
See: https://github.com/SiliconLabs/arduino/tree/main/libraries/EEPROM

[technoblogy]

When will 2.1.0 be available in Arduino Boards Manager? It's still only offering me 2.0.0.

[silabs-bozont]

2.1.0 should be out by now - if the IDE doesn't offer the upgrade you can paste https://siliconlabs.github.io/arduino/package_arduinosilabs_index.json in the 'Additional Boards Manager URLs' field - then the update will be visible.

Thanks - I've updated and will try it out.
